Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a fixing device for a power cord of a general household electric iron.

BACKGROUND ART Conventionally, this type of power cord fixing device has a structure as shown in, for example, Japanese Utility Model Application No. 54-181194.

That is, the power cord was bent and fitted into a groove provided in the handle, and was fixed by pressing with a back plate. Problems to be Solved by the Invention However, with such a configuration, the power cord cannot be fixed in a predetermined position.

In other words, power cords usually have a twisted structure in which two core wires are twisted together to improve durability when bent during use. With a fixed type, the overlapping direction of the core wires differs depending on the twist, so the fitting dimension between the groove and the power cord is not constant due to the difference in the overlapping direction, and even if pressure is applied by the lid, it will not stay in the specified position. There was a problem that it could not be maintained.
Means for Solving the Problems Accordingly, in the present invention, the core wires are separated at the terminal portion of the power cord, and each core wire is fitted into the groove separately and fixed.

action The effect of this technical means is as follows.

In other words, the end of the power cord is separated and each core wire is fitted into the groove, and the protrusion provided on the lid body presses and fixes it into the groove.Since the diameter of the core wire is constant, it is easy to fit into the groove. Since the fitting size can be set constant without variation, it can be securely fixed with the necessary holding force, and it can be easily attached because it is less dependent on the pressing force of the lid. Embodiment Hereinafter, one embodiment will be described based on the accompanying drawings.

In Figures 1 to 4, 1 is a base in which a heater 2 whose electricity is controlled by a thermostat (not shown) is embedded, 3 is a cover thereof, 4 is a handle, and 5 is a temperature adjustment knob provided on the handle. , 6 is a hollow portion provided at the rear of the handle 4, covered by a lid 7, and facing a terminal 8 of a thermostuft connected to the front heater circuit. 9 is a screw for attaching the lid 7 to the handle 4; 10 is a bushing 11;
The power cord is inserted through the lid body 7 through the power cord, and the terminal part separates the core wires 12 from each other and connects the tip with a screw to the terminal 8.
is connected to.

Reference numeral 13 denotes a locking groove formed in the inner wall of the handle 4 defining the hollow portion 6, which is bent in the left-right direction and recessed, into which the core wires 12 are respectively inserted and engaged.

Reference numeral 14 denotes a protrusion provided on the inner surface of the lid 7 facing the locking groove 13. By attaching the lid 7 to the handle 4, each core wire 12 of the power cord 10 is fixed in the locking groove 13. It is something to do.

In the above configuration, the core wire 12 is the integrated power cord 1
Since the power cord 10 is separated from the power cord 10 and fitted into the locking grooves 13 separately, and the fitting dimensions are always constant, even if an outward tension is applied to the power cord 10, the holding position will not change. There is no slippage in the tensile direction, and the tension does not reach the connection with the terminal 8.

Effects of the Invention In the present invention, the core wires are separated at the end of the power cord and fitted into the locking grooves separately, so that the fitting dimensions with the locking grooves are constant, so that the core wires can be held depending on the fitted state. In addition to being able to stably fix the cord without causing any variation in force, it also has the following effects.

That is, since a predetermined holding force can be obtained without complicatedly bending the power cord within the hollow portion, ease of assembly is improved and the structure of the locking groove can be simplified. Note that if the cord is arranged linearly opposite the outlet of the bushing, even if the bushing is movable, the movement of the bushing will not be restricted by the cord and will operate smoothly.
